We developed a systematic method for optimizing the design of depth-graded multilayers for astronomical hard-x-ray and soft-gamma-ray telescopes based on the instrument's bandpass and the field of view. We apply these methods to the design of the conical-approximation Wolter I optics employed by the balloon-borne High Energy Focusing Telescope, using W/Si as the multilayer materials. In addition, we present optimized performance calculations of mirrors, using other material pairs that are capable of extending performance to photon energies above the W K-absorption edge (69.5 keV), including Pt/C, Ni/C, Cu/Si, and Mo/Si.
我们基于仪器的带通和视场，开发了一种用于优化天文硬X射线和软伽马射线望远镜深度渐变多层膜设计的系统方法。我们将这些方法应用于气球搭载的高能聚焦望远镜所采用的圆锥近似沃尔特I型光学器件的设计，使用W/Si作为多层膜材料。此外，我们还给出了使用其他材料对的镜子优化性能计算结果，这些材料对能够将性能扩展到高于W K吸收边（69.5 keV）的光子能量，包括Pt/C、Ni/C、Cu/Si和Mo/Si。
